Braking resistor

The brake resistor is mainly used to consume the excess energy that the power grid cannot absorb in the electric brake to ensure that the intermediate DC circuit voltage does not exceed the limit. Brake resistor is composed of brake resistance, cooling fan, thermostat, metal box and other components.Each bullet train is equipped with one brake resistor with two separate brake resistors; each brake resistance is forced air cooled and powered by the 400VAC circuit of the traction converter cooling system.
